ROUND: Deproject Spirals or Elliptical Images


\begin{command}
\item[Form: ROUND dest source {[PA=f]} {[E=e]} {[C=(r,c)]} {[NO...
...l intensities}
\item[SINC]{use high-accuracy sinc interpolation.}
\end{command}

ROUND will deproject an image by assuming that the true shape of the object is a circle projected into an ellipse of a given position angle, ellipticity (1-b/a) and center. Creates a new image in the `dest' buffer from the original image in the `source' buffer.

The SINC keyword instructs ROUND to use high-accuracy sinc interpolation instead of the default bilinear interpolation algorithm.

The NORM keyword is used to renormalize the pixel intensities (surface brightness/pixel) in the transformed image.
